Non-Isolated Resistive Programming Of Current Calibration - Xantrex Watt Series Programmable DC Power Supply XG 850 Operating Manual

Non-isolated Resistive Programming of Current Calibration

Important:
calibration procedure again but use the intended operating resistance level in
steps 2 and 3.
To calibrate the non-isolated resistive programming of current:
1. Short the main output with a shunt. Connect a multimeter to measure
2. Connect the 4.000 kΩ resistor to the non-isolated connector (APG -
3. Set the resistive APG level to 4 kΩ. The SCPI command is:
4. Set the input source as Resistive Non-Isolated for Current
5. Turn the main output to On by pressing the OUTPUT ENABLE Main
6. Enter the interactive calibration mode by sending the SCPI command:
7. Press the terminal keys – or + to reduce or increase the main output
8. Press any key other than the + or – keys to exit from interactive
